NETGEAR 8800 User Manual broadcast NTP updates. In addition, the switch supports the configured setting for Greenwich Mean time (GMT) offset and the use of Daylight Saving Time. Configuring and Using SNTP To use SNTP: 1. Identify the host(s) that are configured as NTP server(s). Additionally, identify the preferred method for obtaining NTP updates. The options are for the NTP server to send out broadcasts or for switches using NTP to query the NTP server(s) directly. A combination of both methods is possible. You must identify the method that should be used for the switch being configured. 2. Configure the Greenwich Mean Time (GMT) offset and Daylight Saving Time preference. The command syntax to configure GMT offset and usage of Daylight Saving Time is as follows: configure timezone {name } {autodst {name } {} {begins [every | on ] {at } {ends [every | on ] {at }}} By default beginning in 2007, Daylight Saving Time is assumed to begin on the second Sunday in March at 2:00 AM, and end the first Sunday in November at 2:00 AM and to be offset from standard time by one hour. If this is the case in your time zone, you can set up automatic daylight saving adjustment with the command: configure timezone autodst If your time zone uses starting and ending dates and times that differ from the default, you can specify the starting and ending date and time in terms of a floating day, as follows: configure timezone name MET 60 autodst name MDT begins every last sunday march at 1 30 ends every last sunday october at 1 30 You can also specify a specific date and time, as shown in the following command: configure timezone name NZST 720 autodst name NZDT 60 begins every first sunday october at 2 00 ends on 3 16 2004 at 2 00 The optional time zone IDs are used to identify the time zone in display commands such as show switch {detail}. Table 14 describes the command options in detail. Table 14. Time Zone Configuration Command Options tz_name GMT_offset autodst Specifies an optional name for this timezone specification. May be up to six characters in length. The default is an empty string. Specifies a Greenwich Mean Time (GMT) offset, in + or - minutes. Enables automatic Daylight Saving Time. 90 | Chapter 3.
